938 6812 d 2 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
703 6870 d 8 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
534 6910 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6910 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6922 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
413 6957 d 21 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.
 
315 6998 d 13 h jermar /SPARTAN/trunk/arch/ia32/ Make IA-32 userspace stack be aligned on doubleword boundary.
In userspace(), mark "eax" as clobbered register.
 
144 7046 d 7 h vana /SPARTAN/trunk/ Coding style fix  
142 7046 d 8 h vana /SPARTAN/trunk/arch/ia32/src/ Typing error fixed  
141 7046 d 8 h vana /SPARTAN/trunk/ Clear IOPL on start of system on all CPUs and clear NT before all irets.  
125 7051 d 23 h jermar /SPARTAN/trunk/ Huge indentation fix.  
106 7094 d 7 h jermar /SPARTAN/trunk/ IA-32 fixes.
Use kernel addresses instead of physical addresses in map_page_to_frame().
Physical addresses are supposed to only be exported to mm hardware.
Because of this fix, userspace is functional again.

Remap EGA videoram to (0x80000000 + videoram) and change the ega driver to work with the new address.

Minor cosmetics through out the code.
Changes in linker scripts.
 
65 7117 d 2 h decky /SPARTAN/trunk/arch/ia32/ doxygen-style comments  
22 7141 d 2 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.  
15 7149 d 2 h jermar /SPARTAN/trunk/ Introduce macros CPU, THREAD, TASK and use them to replace the->cpu, the->thread, the->task.
Later on, this will make it possible to reference *current* cpu, thread and/or task without the aid from virtual memory.
